Ответ:
- Переставим слагаемые: 38 + 62 + 45 = 100 + 45 = 145.
- 75 + 25 + 28 = 100 + 28 = 128.
- 43 + 57 + 19 = 100 + 19 = 119.
- 125 + 75 + 48 = 200 + 48 = 248.
- (4 × 25) × 7 = 100 × 7 = 700.
- (6 × 5) × 13 = 30 × 13 = 390.
- 18 × (5 × 2) = 18 × 10 = 180.
- 16 × 20 + 16 × 3 = 320 + 48 = 368.
- 12 × 30 − 12 × 2 = 360 − 24 = 336.
- 27 × (4 + 6) = 27 × 10 = 270.
- (35 + 65) × 8 = 100 × 8 = 800.
- 600 ÷ 6 = 100.
- 600 ÷ 6 = 100.
- (42 ÷ 7) × 5 = 6 × 5 = 30.
- (720 + 80) ÷ 8 = 800 ÷ 8 = 100.
